June 24, 1930. F. A. CHAPMAN ET AL IN TERNAL COMBUSTION ENGINE HEATERFiled Sept. 13. 1928 814410141 01 ;FB.Eh a pman WKDtvis Y Patented June24, 1930 UNITED STATES FRIED A. CHAPIEAN AND WILLIAEEINTERNAL-GOMBUSTEGH- Application filed. September 1 The invention aimsto facilitate the starting of a cold engine utilizing a volatile liquidfuel as the motive medium.

In accordance with the invention, a heater of novel and peculiarstructure is disposed in close proximity to the oil pan and is connectedwith the Water cooling system of an internal combustion engine to warmboth the oil and the Water with the result that starting of the enginewhen cold is greatly facilitated which is a dcsideratum.

' While the drawings illustrate a preferred embodiment of the inventionit is to be understood that in adapting the means to meet specific needsand requirements, the design may be varied and such other changes in theminor details oi construction may he resorted to Within the scope of theinvention as claimed, Without departing from the spirit thereof.

F or a full understanding of the invention and the merits thereofreierence is to be had to tl e following description and the drawingshereto attachec, in which:

Figure 1 is a side View illustrative of an embodiment of the invention.

Figure 2 is enlarged transverse sectional view.

Figure 3 is vertical longitudinal sectional view of the heater. 1

Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawings by likereference characters.

The numeral 1 denotes an engine of the internal combustion type 2 theoil pan or crank case, and 3 the radiator through Which the Water iscirculated for cooling the engine When in action. These parts are ofWell known construction and arrangement and are illustrated todemonstrate the applica tion of the invention, which resides in theheater and peculiar construction and arrangementthereof.

The heater is designated by the numeral 4 and is elongated and ofsemi-circu r formation in cross section. The heater 1S hollow and theiii sine is depressed as indicated at 5, to receive an element 6 Whichmay be aheating unit of any type. The space 7 formed between the innerand the outer is of the l 1 iv is i semi-circular outline g; the coo ngmedium engine is circulated tl ercth ough.

er costar cd n the Water 19. Chet of the engine as will be rea W'ciated.

Suitable r-icans are emoloyec for secnrinh id showm yed to retain thedevice elemen 6 the elect Q Which a and which 0- 2 electric currentwhereby heat is gone *ated in a manner Well understood.

The nume'al 11 denotes an electric cord which may is d from a source ofcurrent supply and Whicn is adapted to be plugged into a sociret l2 oneend of the heater and to Which the terminals of the *ire Wound about thecoil of the heating unit are connected.

-When it is r {hired to Warm a cold engine to make starting thereof easyan electric current caused to flow through the Wire of the heatingelement and the heat thus generated warms the oil in the pan 2 and theWater in th cooling system of the engine. In a compa 'atively short timethe engine is sufiiciently heated to render starting easy and,

at the same time, the oil is warmed so as to flow and enable theoperating parts to move easily.

What is claimed is:

In an internal combustion engine, a heat er comprising a hollow body ofsemi-circular formation in cross section and having an open-sided recessformed in its flat side, said flat side being engaged against the oilpan of the engine whereby the recess is closed by said pan, a heatingunit mounted in the recess, and means connecting the hollow body Withthe Water jacket and radiator of the engine.

In testimony whereof We aflix our signatures.
